Answer:
270 seconds
Step-by-step explanation:
Melissa's time = x seconds
Abby's time = (x + 30) seconds
Abby walks at a speed of 8 feet per second, and Melissa walks at a speed of 9 feet per seconds.
But, speed =
For Abby,
8 =
distance = 8(x + 30) ................. 1
for Melissa,
9 =
distance = 9x ............. 2
From equations 1 and 2, for the same distance;
8(x + 30) = 9x
8x + 240 = 9x
x = 240 seconds
Abby's time = (x + 30)
= (240 + 30)
= 270 seconds
So that Abby has been walking for 270 seconds when both students had walked exactly the same distance.
The answer is c because it reflect a reflection over the x axis making it look like a M
Answer:
Step-by-step explanation: Area of triangle is base x height divided by 2. So do 8 + 8 to get the base which is 16m. 16 x 8 = 128/2 = 64 m^2
Area of a 1/4 circle is PI Radius ^2 then divided by 4. So *8^2 = 201.06/4 = 50.265 m^2
So to get the area of the entire figure you need to find the perimeter of the figure. So you should use the perimeter formula for each shape and then add all your perimeters of each shape. 1/4 Circle perimeter formula is C=2πr/4 . Perimeter of a square is P = 4a. Perimeter of a triangle is P =
a + b + c . Circle solving 50.27/4 = 12.5675 m^2. Triangle solving 8 + 8 + 16 = 32 m ^2 . Square solving 4 x 8 = 32 m ^ 2 .
This was so confusing and I dont know if this helps or not but I tried my hardest!
